I'm trying to access the bios on this motherboard on start up and I have two keyboards to work with (both being USB).

One is the apple keyboard and the other is an everglide keyboard. I've not had any problems before with the apple keyboard (which I normally use to access the bios) until now. On start up I hit delete on the keyboard to get into bios and it rolls right past the screen onto starting up.

What is wrong with this thing? Why is it ignoring my keyboard on boot?

Maybe USB legacy mode isn't set in the BIOS? Some older motherboards require PS/2 keyboards to access the BIOS.
